Benjamin Tosado knows Microsoft Lync, so his review of the Windows Phone Lync client is worth your time. Lync is an enterprise-grade instant messaging client, so it makes sense that any enterprise installation that includes Windows Phone is going to be looking to have Lync on their smartphones.

While this first go at a mobile client has some good features, there's still a lot missing. One of the greatest benefits that Microsoft Lync has from a PC perspective is integration with other Microsoft applications. Presence and click-to-communicate capabilities are available across the Microsoft Office suite. This type of integration is still absent from the mobile experience. The e-mail and contact interfaces on the phone don't expose presence information, so a user is forced to jump back and forth between the Lync interface and other applications on the phone.

Lync for Windows Phone gets the basic job done even though it's a bit rough at the edges. It's recommended, but Tosado is looking for more in the next version.

And I suspect the roadmap has many of these features covered. Making Windows Phone into a platform that can easily be dropped into the IT department of big businesses should be high up on Microsoft's to-do list, especially with the issues that Blackberry are having at the moment. Lync is one piece of that important jigsaw.
